If you want a super-steady shot from your iPhone's camera—or want to take a picture of yourself from a tripod—you can actually use the volume button on your iPhone's headset to take a picture.

One of iOS 5's coolest shortcuts is the ability to take a picture using your phone's volume up button, making it act a bit more like a real camera. However, what you may not have realized is that using the volume up button on the Apple Remote Earphones—which come with every iPhone—will also take a picture. That way, you can put your iPhone on a DIY tripod and take a picture of you and your friends from far away, or just take a super-steady picture without your hands muddying up the shot. It even works with some Bluetooth headsets, too—though your mileage may vary with non-Apple peripherals. Photo by With Associates.
